Ikhwalithi Ephakeme Yenziwe Ngokwezifiso I-Powell Prism Yezinsimbi Zezokwelapha

Powell lens
I-Powell lens iwukugxuma kwe-quantum phambili ekusebenzeni kwejeneretha yomugqa phezu kwelensi yesilinda elula. Ilensi yesilinda ikhiqiza ulayini ongakhanyi kahle, owodwa onqunyelwe i-non-uniform, i-Gaussian laser beam. Uphahla oluyindilinga lwelensi ye-Powell empeleni luyijiko le-aspheric elinezinhlangothi ezimbili eliyinkimbinkimbi elikhiqiza inani elikhulu lokuphambuka okuyindilinga esabalalisa kabusha ukukhanya emugqeni; ukwehlisa ukukhanya endaweni emaphakathi ngenkathi ukhulisa izinga lokukhanya emaphethelweni omugqa. Umphumela uba ulayini okhanyisiwe ofana kakhulu osetshenziswa kuzo zonke izinhlobo zezicelo zombono womshini; kusukela ekuhlanganiseni kwe-bio-medical kanye nemoto kuya ekukhiqizweni kwamakhukhi we-chocolate chip.

Ukusebenza kwelensi ye-Powell nezici zomzimba ziqhutshwa ububanzi be-beam. Umehluko obaluleke kakhulu ukuphrinta konyawo lwefeni ephambukayo kubuso obuyisicaba obuphumayo obusebenza njengendawo ekhwezayo. Kufanele kuqikelelwe ukuthi ihadiwe ekhwezwayo ayikusiki ukukhanya okuphambukisayo.

Ilensi ye-Powell ifana neprism eyindilinga enomugqa wophahla olugobile. Ilensi iyijeneretha yomugqa we-laser, enweba ugongolo oluncane lwelaser lube umugqa oqondile okhanyiswe ngokufanayo.
